IEIIJE CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK COMPOSITE PILE This invention relates to composite piles. More'specifically stated the invention relates to the construction of composite piles, such as piles formed by driving a wood pile into the ground and thereafter placing a metallic shell on the wood pile, further driving the pile and then filling the shell with concrete. The lower pile section or wood pile is usually formed with a tenon at its upper end to which the shell is secured. It has been found that the driving of the'wood pile and shell. has injured and at times crushed the tenon.

This invention has for its salient object to provide improved connecting means or driving connections for transmitting the impacts or blows of the pile'hammer to the wood pile as the latter is driven below the ground level.

Another object of the invention is to provide drive transmitting means of the char- I acter specified so constructed and arranged that the force of thedriving impacts will not be concentrated on the tenon, but will be transmitted to the main body of thewood pile.

Anotherobject of the invention is to provide a structure of the character specified that can be easily and quickly placed in operative position intheshell and withdrawn therefrom after the pile has been driven.

Another object of the invention is to provide a simpleand practical drive transmitting means.

Further objects of the invention will appear from the following specification taken in connection with the drawing which forms a part of this application, and in which.

Fig. 1 .is a longitudinal elevation partly in section of drive transmitting and shell bracing means constructed in accordance with the invention;

Fig. 2 isa view similar to Fig. 1, but taken at right angles thereto;

1 and Fig. 3 is a top plan view of the structure Fig. 5 is an elevational view on an enlarged scale, taken at right angles to Fig. 4.

The invention briefly described consists of drive transmitting and shell reinforcing or bracing means comprising a head adapted to receive the impacts of the pile driver or hammer, a longitudinally extending tubularmember connected to the head and having a socket or recess block at the lower end thereof. adapt-- ed to fit over the tenon of a wood pile, the' socket being so arranged that the walls thereof will bear against the end of the wood pile surrounding the tenon in addition to the bearing of the inner end of the socket against the outer end of the tenon. Means is also con- 6 nected to the head for reinforcing and bracing the metallic shell which is positioned on the upper endof the wood pile during the driving operation. This means consists of a pair of curved or substantially semi-cylindri- 7 'cal leaves or members which are so connected to each other that movement of one of the members relative to the other in one direction .willca-u'se the members to move laterally relative to each other and into gripping engage ment with the inner surface of the shell.

In the form of the invention illustrated, the leaves .or members are connected by links which have a toggle action in forcing the leaves apart. The leaves are, furthermore," so connected to the headthat after the pile has been driven a lifting action on the head will raise one of the leaves prior to the lifting of the other leaf, thus releasing the leaves from their gripping action on the shell.

Further details of the invention will appear from the following description.

In the particular embodiment of the inven tion illustrated in the drawing there is shown a woodpile 10 having a tenon 11 extending upwardly from its upper end. A pin 12 extends through the tenon and'is utilized in connection with means for locking the shell to the tenon after the pile 10 has been driven.

A metallic shell 15 is bent inwardly at its lower end, as shown at 16, and upwardly, as shown at 17. The portion 16 is provided with oppositely extending notches to receive the projecting endsof the pin 12 when the shell is lowered to' the position shown in Fig.

1. A pan 18 is secured to the pile 10 in any suitable manner as by spikes 19 and the shell rests in the pan, the portion 17 thereof surrounding the tenon 11.

After the pile 10 has been driven to the ground level and the shell has been placed thereon in the manner described, the pile is further driven into the ground in the manner hereinafter set forth.

A head 20 has a centrally disposed depression 21 for receiving the blows of the pile driver or hammer and is provided witha central boss 22 and an annular flange 23. A tubular drive transmitting member 24 is secured to the boss 22 at its upper end and is provided at its lower end with a socket 25 having a stud 26 which projects into the lowerend of the member 24 and is secured therein. The socket 25 is so proportioned as to fit over the tenon 11 and'the walls of the socket are notched, as shown at 27, to receive the outer ends of the pin 12. The depth of the socket is so proportioned that theends of the walls will engage the upper end 28 of the pile 10 and the inner end 29 of the socket will engage-the outer end of the tenon 11.

The blows from the pile apparatus or hammer are'transmitted from the head 20 through the member 2a to the pile 10.

Suitable bracing or reinforcing means is provided for :the shell 15. This means consists of a pair of longitudinally extending semi-cylindrical leaves 30 and '31 which are preferably double in thickness. The leaves are connected 'to each other at diametrically opposite points by a plurality of sets of l inks 32 and 33. These links, as shown in Fig. 5, are inclined relative to the axis of the shell and the leaves are so connected to the head that longitudinal movement of one of the leaves is permitted relative to the'other. The leaf 30, as shown in Fig. 3, is secured to the 1 1 H nead by means of a hollow pin 3:) which eX- tends through the flange 23 and through the tubular member 24 and boss 22. The other loaf '31 has a slot 36 for receiving the pin 35. It wi l be obvious that as a downward force is exerted on the leaf 30 the links 32 and 33 will tend to spread the leaves away 'f-romeach other or, in other words, force the leaves into firm gripping engagement with the shell 15. Furthermore, after the pile has been driven and the head 20 is lifted the leaf '30 will be raised before the pin engages the upper endof the slot 36 and the leaf 31, thus the leaves will be moved toward each other and out of gripping engagement with the inner surface of the shell 15.

From the foregoing description it will be clear that simple, practical and eflicient means have been designed for transmitting the pile driver or hammer impacts to a pile through a shell mounted thereon and also for reinforcing and bracing the shell during the driving operation. It will also be clear that after the pile has been driven the drive transmitting means and the shell bracing means can be easily and quickly withdrawn by lifting the head of the transmitting and bracing means.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
